The results suggest that the least energy was consumed for crushing the electrode materials of anodes and cathodes and highest energy was used to crush The low-temperature route shows different possibilities to combine sieving and air classification. One reason is the selective decoating of anode coating during battery crushing as its adhesive forces on the Cu foil are lower compared with cathode coating on the Al foil [5, 128]. Hence, the black mass created during the initial crushingMechanical and physical processes of battery recycling

Pretreatment options for the recycling of spent lithium-ion batteries
The deactivated batteries first go through primary crushing to expose and separate components like the separators, followed by magnetic separation to recover the iron flakes. Afterward, the battery components such as the anode and cathode sheet are further crushed to specific sizes. Dry crushing of the spent LIBs has been used in The frequent safety accidents involving lithium-ion batteries (LIBs) have aroused widespread concern around the world. The safety standards of LIBs are of great significance in promoting usage safety, but they need to be constantly upgraded with the advancements in battery technology and the extension of the application scenarios.

Ecological Recycling of Lithium-Ion Batteries from Electric
For crushing battery modules from EV the usage of an inert atmosphere remains with no alternative. After the removal of electrolyte components by drying, separation of the different materials is the main goal. A "mild" second crushing step via a cutting mill increases the yield of black mass to 75%. Most importantly, this process step The battery will be broken near the 6 mm displacement position, and a large amount of shear failure occurs inside the battery.
